Went into Netflix on my PS4 last night for the first time in a while and it asked me "Who's watching?" and showed me three profiles: mine and two others I did not add. Just checked online and while one of them has only watched one movie, the other has an 'interesting' history. So... I'm assuming my Netflix account was 'hacked' in some fashion and these were a couple of freeloaders? Deleted both profiles (sorry two and ubuntu), changed my password and did the 'sign out of all devices' thing, guess we'll see what happens next.
